When you send a PayPal-enabled invoice to your client, they'll receive an email with a link to open and pay the invoice, like in the image below.
When they click the View or Pay button, they are taken to an online version of your invoice, where the option to pay either by a PayPal account or their credit/debit card is presented.
Note that your customer does not need to have a PayPal account to pay you.
Your client can choose the method of payment they prefer, then enter their details on the screen.
For PayPal, they'll be given the option to sign into their PayPal account.
For Debit or Credit, they'll be given a standard online payment form, as seen below.
Once your client submits the payment, they'll receive a confirmation message on screen, followed by an emailed receipt from PayPal for their records.
And that's it! If your client has ever paid for something online before, this should all be familiar and easy for them.
If you run into any issues with your payment, you can reach out to PayPal directly for support.
